Andreescu made the announcement on social media and added she will not be playing in the upcoming Madrid Open.
The 2019 U.S. Open champion adds she’s feeling well and is resting while continuing to follow health and safety guidelines.
Andreescu said the positive test came after she arrived in Madrid.
“After testing negative twice before my flight to Madrid, I was sadly informed that I tested positive upon arrival for COVID-19,” she said in a statement. “Therefore I will not be playing at the Madrid Open later this week.”
“I am feeling good, I’m resting and continuing to follow the health protocols and safety guidelines. I look forward to getting back out on the court very soon.”
Andreescu, the 2019 U.S. Open champion, played at the Miami Open earlier this month, reaching the final against Australian Ashleigh Barty. But the Mississauga, Ont., native was forced to retire in the second set after falling awkwardly earlier in the match and suffering an ankle injury.
Andreescu was also forced to miss 15 months the result of a knee injury, returning to play in the 2021 Australian Open. After winning her first-round match, Andreescu lost in straight sets to Hsieh Su-wei of Taiwan in the second round.
